SPECIFICATION forming part of Letters PatentNo; 656,427, dated August 21, 1900. Application filed December 4, 1899.: Serial No. 739,078. (No model.)

To all whom t may cncerlt:

zen of the United States, residing at Philadelphia, in the 'county of Philadelphia and State of Pennsylvania, have invented certain y new and useful Improvements in SewinglMachine Lap-Seam Fellers, of Awhich the follow#4 ing is a specification, reference being had therein to the accompanying drawings.

This invention relates to an improvement in lap-seam fellers, by means of which the lower or under fold of fabric will at the commencement of the seam be brought out fully to the desired lateral position to insure a perfect fold at the beginning of the work,

and will at all times be held in such position during the formation of the seam, even when turning sharp curves, without any special care on the part of the attendant, and thus imperfect work in forming lapseam fells, and which might otherwise result, will be avoided. To secure the improved resultreferred to, the lower folder of the improved feller is provided with a forwardly-projectingtongue extending beyond the main portion or body of the feller close to the needle of the machine and to a position in line with the forward end of the outer edge ofnthe, passage-way for the lower ply of fabric, or ap proximately so, and outside of the line of the seam formed by the right-hand needle when the feller is used (as is the common practice) on a two-needle sewing-machine. This forwardly-projecting tongue serves to distend the irst part of the lower fold at the com-` mencement of the lapseam to its proper lateral position and to hold it there during the entire formation of the seam without special care by the attendant. few stitches have to be made with themachine running slowly, but with the improved feller the machine may commence to sew at high speed, thus saving considerable time,A

compara-- Ordinarily the first fabric is folded, the saidV wing u. supporting Be it known that I, JAMES T. SHAW, a citithe Wing b, the inner edge b of which serves as a folder for the lower ply of fabric, which rests on the plate A with its edge curled up 'in the passageway e around the said edge b', while the edge of the upper ply of fabric is ycurled down in the passage-way d.

The lower folder of the feller,`consistiug of the lower limb of the wing b, is provided with a forwardly-projecting tongue e, preferably ,curved outwardly, as shown inA Fig. l, and the forward end of which is in line, or approximately so, in the' direction of the feed of the Work with the forward end of the outer edge of the passage=way c for the lower ply of fabric. This forward end of the pro; jecting tongue e extends close to the position of the right-hand needle n of a two-needle sewing machine, with which the lap seam feller is usually employed, the position of the left-hand needle of such machine being denoted at n. a

The improved feller may be provided with any'suitable means for attachment to the work-plate of a sewing-machine, such means for attachment consisting in the present instance of the slide or cover f, similar to a shuttle-race slide, to which the base-plate A of the feller is soldered.

InV the use of the attachment the work is inserted in the usual manner with the edges thereof curled around in the passage-ways c and d, so that they will preferably interhook or interlap when brought together in the final folds. Y With the work in such position the lower fold is completely hidden from the view of the attendant bythe upper .ply of fabric, so that ordinarily, unless special care be exercised, the lower fold will not be properly formed, as it is difficult, if not im'possible, with lap-seam fellers as ordinarily con structed to commence the seam with the lower foldof fabric brought out square at its end,

and there is, moreover, a constant tendency, particularly in turning sharp curves, for the lower fold to escape from its properposition; but this tendency, which unless special care be takenv might result in imperfect work, is elfectually counteracted by the forwardlyprojecting tongue c, comprised by the present invention. As the upper fold is always in IOO 2 J ese/127 sight, and is, moreover, not so much 'infinenced by the feed, there is never any diffe culty inkeeping the upper ply of fabric in proper folding position, so that a. forwardlyprojecting tongue on the upper folder is not necessary. A

Having thus described my invention, I claim `and desire to secure by Letters Patentl. A lap-*seam feller comprising upper and V lower folders, the said lower folder being provided with an outwardly and forwardly pro-A jetiug tongue, as e, extending beyond the main body of the feller so that its forward end will be close to one of the needles of a. v

two-needle sewing-machine.
